鈑金加工是(shi)(shi)(shi)鈑(ban)(ban)金技(ji)術人員需(xu)要(yao)(yao)掌(zhang)握的(de)(de)關(guan)鍵技(ji)術，也是(shi)(shi)(shi)鈑(ban)(ban)金制(zhi)品成(cheng)形(xing)重(zhong)要(yao)(yao)工(gong)(gong)序。它既包(bao)括傳統鑿割下料、沖裁加(jia)(jia)(jia)(jia)(jia)工(gong)(gong)、沖壓成(cheng)形(xing)等(deng)(deng)方(fang)(fang)法(fa)及(ji)工(gong)(gong)藝(yi)參數(shu)，又包(bao)括各種工(gong)(gong)況沖壓模(mo)具(ju)(ju)(ju)結(jie)構及(ji)工(gong)(gong)藝(yi)參數(shu)、各種設(she)備工(gong)(gong)作原理及(ji)操(cao)作方(fang)(fang)法(fa)，還包(bao)括新沖壓技(ji)術及(ji)新工(gong)(gong)藝(yi)。金屬(shu)(shu)(shu)(shu)板材加(jia)(jia)(jia)(jia)(jia)工(gong)(gong)就(jiu)叫鈑(ban)(ban)金加(jia)(jia)(jia)(jia)(jia)工(gong)(gong)。具(ju)(ju)(ju)體譬如(ru)利用(yong)板材制(zhi)作煙囪、鐵桶、油箱油壺、通風管(guan)道、彎(wan)頭大(da)小(xiao)(xiao)頭、天(tian)圓地方(fang)(fang)、漏斗(dou)形(xing)等(deng)(deng)，主要(yao)(yao)工(gong)(gong)序是(shi)(shi)(shi)剪鑿、折彎(wan)扣邊、彎(wan)曲(qu)成(cheng)形(xing)、焊接(jie)、鉚接(jie)等(deng)(deng)，需(xu)要(yao)(yao)一定幾何知識。鈑(ban)(ban)金件(jian)(jian)(jian)就(jiu)是(shi)(shi)(shi)薄板五金件(jian)(jian)(jian)，也就(jiu)是(shi)(shi)(shi)可以通過沖壓，彎(wan)曲(qu)，拉伸(shen)等(deng)(deng)手段來加(jia)(jia)(jia)(jia)(jia)工(gong)(gong)零(ling)件(jian)(jian)(jian)，一個大(da)體定義(yi)就(jiu)是(shi)(shi)(shi)在(zai)(zai)加(jia)(jia)(jia)(jia)(jia)工(gong)(gong)過程中厚度(du)(du)(du)不(bu)發生(sheng)變化(hua)的(de)(de)零(ling)件(jian)(jian)(jian)。相(xiang)對(dui)應的(de)(de)是(shi)(shi)(shi)鑄(zhu)造(zao)件(jian)(jian)(jian)，鍛壓件(jian)(jian)(jian)，機械加(jia)(jia)(jia)(jia)(jia)工(gong)(gong)零(ling)件(jian)(jian)(jian)等(deng)(deng) 加(jia)(jia)(jia)(jia)(jia)工(gong)(gong)。cold working of metal 通常指金屬(shu)(shu)(shu)(shu)的(de)(de)鑿削(xue)(xue)(xue)加(jia)(jia)(jia)(jia)(jia)工(gong)(gong)，即用(yong)鑿削(xue)(xue)(xue)工(gong)(gong)具(ju)(ju)(ju)從金屬(shu)(shu)(shu)(shu)材料（毛坯）或工(gong)(gong)件(jian)(jian)(jian)上鑿除多余(yu)金屬(shu)(shu)(shu)(shu)層(ceng)，從而使工(gong)(gong)件(jian)(jian)(jian)獲(huo)得具(ju)(ju)(ju)有一定形(xing)狀(zhuang)、尺寸精(jing)度(du)(du)(du)和表(biao)面粗(cu)(cu)糙度(du)(du)(du)的(de)(de)加(jia)(jia)(jia)(jia)(jia)工(gong)(gong)方(fang)(fang)法(fa)。如(ru)車削(xue)(xue)(xue)、鉆(zhan)削(xue)(xue)(xue)、銑削(xue)(xue)(xue)、刨(bao)削(xue)(xue)(xue)、磨削(xue)(xue)(xue)、拉削(xue)(xue)(xue)等(deng)(deng)。在(zai)(zai)金屬(shu)(shu)(shu)(shu)工(gong)(gong)藝(yi)學中，與加(jia)(jia)(jia)(jia)(jia)熱加(jia)(jia)(jia)(jia)(jia)工(gong)(gong)相(xiang)對(dui)應，冷(leng)(leng)加(jia)(jia)(jia)(jia)(jia)工(gong)(gong)則指在(zai)(zai)低于再結(jie)晶溫度(du)(du)(du)下使金屬(shu)(shu)(shu)(shu)產(chan)生(sheng)塑性變形(xing)的(de)(de)加(jia)(jia)(jia)(jia)(jia)工(gong)(gong)工(gong)(gong)藝(yi)，如(ru)冷(leng)(leng)軋、冷(leng)(leng)拔、冷(leng)(leng)滾、沖壓、冷(leng)(leng)擠壓等(deng)(deng)。冷(leng)(leng)加(jia)(jia)(jia)(jia)(jia)工(gong)(gong)變形(xing)抗(kang)力(li)大(da)，在(zai)(zai)使金屬(shu)(shu)(shu)(shu)成(cheng)形(xing)的(de)(de)同(tong)時(shi)，可以利用(yong)加(jia)(jia)(jia)(jia)(jia)工(gong)(gong)硬化(hua)提(ti)高(gao)(gao)工(gong)(gong)件(jian)(jian)(jian)的(de)(de)硬度(du)(du)(du)和強度(du)(du)(du)，但會使塑性降(jiang)低。冷(leng)(leng)加(jia)(jia)(jia)(jia)(jia)工(gong)(gong)適(shi)于加(jia)(jia)(jia)(jia)(jia)工(gong)(gong)截(jie)面尺寸小(xiao)(xiao)，加(jia)(jia)(jia)(jia)(jia)工(gong)(gong)尺寸和表(biao)面粗(cu)(cu)糙度(du)(du)(du)要(yao)(yao)求較高(gao)(gao)的(de)(de)金屬(shu)(shu)(shu)(shu)零(ling)件(jian)(jian)(jian)。
